Rihanna looked down in the dumps as she tried to maintain her regular routine after an alleged stalker sent her gun threats via social media.
The R&B star, 27, was seen heading for the gym in the SoHo neighborhood of New York on Monday and appeared subdued, dressed down in workout gear and wearing a large pair of sunglasses.
It follows the news that law enforcement continues to search for the man who posted the threatening tweets, including one of a gun and bullets.
